9.1.2.2 Answering a call with the tele-device.
A call is answered normally by lifting the tele-device handset or allowing the device
to answer automatically.
If the call has been answered by the handportable , it can be transferred to the tele-
device as follows: Lift the tele-device handset (or press ON LINE from the telefax),
and press the handportable HF key.
9.1.2.3 Terminating a call.
The call is terminated normally by returning the handset to its cradle.
The call may also be terminated by pressing the lightning key on the handportable.
The busy signal will then be heard from the tele-device handset. Do not forget to
replace the tele-device handset, as the line interface uses power from the handport-
able battery.
